Blimey it's a new Overwatch map, hero and animated short

It's a bumper night for Overwatch at BlizzCon 2017 - there's both a new hero and a new map coming!
The new hero is Moira, a support healer. She can teleport - an ability called Fade - and she produces beams and orbs that heal and drain. Her ultimate looks like a combined super-beam that heals all allies caught in it, or drains all enemies.
